Resource ID#: 371

Primary Type: Lesson Plan

View Site

Students will experience the historical discovery of fossils that increasingly link whales to earlier land-dwelling mammals. This experience reveals how scientists can make predictions about past events, based on the theory and evidence that whales evolved. This lesson also provides confirmation, with multiple independent lines of evidence, that there is a series of intermediate forms, showing gradual accumulation of changes, linking certain terrestrial mammal groups with modern whales.
